Emission factors for transport
These datasets contain fleet weighted road transport emission factors by vehicle type, for hot exhaust, cold start exhaust, evaporative emissions and tyre and brake wear; transport primary NO2 emission factors; NOx speed-related emission functions (COPERT 4v8.1) and vehicle fleet composition projections (Base 2011).
These versions have been superceded by the more recent versions above. The factors within them may not be directly comparable with more recent versions due to changes in the methods and raw emission factors used to derive them.
